JOHN MINOR BOTTS LEWIS, 0F LYN CHBURG, VIRGINIA, ASSIGNOR TO COWMATIG CORPORATION, OF LYNGHBURG, VIRGINIA, A CORPORATION OF VIRGINIA.

ANIMAL-STANCHION.

Specification of Letters Patent.

Patented Apr. 20, 1920.

Application filed July 16, 1919. Serial No. 311,290.

To all whom it may concern Be it known that I, Jon M. B. Lnwrs, a citizen of theUnited States, residing at Lynchburg, in-the' county of Campbell and State of Vir inia, have invented certain new and useful Fmprovements in Animal-Stanchions, of Which the following is a specilication.

My invention relates to new and useful improvements in animal stanchions, and has for its object the provision of a stanchion which may be readily opened.

A further object of the invention is the provision of a stanchion of the type described which cannot be accidentally opened by the horns of the animal.

A still further object is the provision of such a device simply and inexpensively constructed, parts of which are readily assembled.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a side elevation, partly in section, of my device;

, Fig. 2 is a side elevation of a latch portion thereof;

Fig. 3 is a plan view of the latch mechanism;

Fig. 4 is a detached view of the latch mechanism, parts being arranged in juxtaposition;

3 .Fig. 5 is a view of the bottom pivotal connection of the stanchion, parts being detached; and 40.

Fig. e is a section on 11m 6-6 of Fig. 1. Referring now more particularly to the (drawings, my stanchion is shown as com- I prising a pair of oppositely bowed tubular arms A and Secured to the upper end of the arm A is a member 2, which is bifurcated to form side frames 3, the outer ends 4 of which are slightly out-turned. .A pivot 5 mounted in the arms 3 has mounted thereon a lever 6.

One end of the lever 6 is enlarged, as at 7,

and-provided with a central aperture 8. v

$ecured centrally to the lever 6 and depending therefrom is an arm 10 having a lug 11, to which is secured byany suitable means, a compression spring 12.

The upper end of the arm A is provided with a member 13 having lugs 14, 15, thereon. It will be seen that when the arm'A' is swung to the closed position, the lug 14 engaging the spring 12 forces the enlargedend of the lever 6 into engagement with the lug 15, latching the two parts together. Means for limiting the downward movement of the enlarged end of the lever 6 is shown as comprising lugs 8 engaging notches 3 with the members 3.

The supporting chain 16 of the stanchion is secured to the pivot 5 by means of eyes 17 straddling the pivot of the lever 6.

j The lower end of the arm A is provided with a member 18 which is bifurcated to form pivot faces 19 supplied with a central aperture 20. Upon the lower end of the arm A is arranged a complementary n1en1ber 21 having a cut-out portion 22 and supplied with a hook 23. It will be noted that the chain 27 which forms a securing means for the lower end of the stanchion may be readily inserted while the parts are d sengaged but cannot be removed while the parts are assembled, as shown in Fig. 1.

The parts are held in assembled position by means of a bolt 26 and their connection is protected from dust falling particles of rain, etc., by means of a cover member 24 ormed integrally with the complementary member 21. Any suitable means for preventing the parts of the stanchion from opening too wide or striking the floor when opened may be provided. I have shown this as comprising a lug 29, which engages the hook 23 limiting the movement of the arm A.

It will be obvious that by depressing the end 9 of the lever 6 the stanchion is freed from the neck of the animal. To prevent this being done by contact with the horns of the animal, the arms 3 of the member 2 have been enlarged as at 2 It will be obvious to those familiar with the art that many minor changes could be made without departing from the spirit of extremities of the ends of said bifurcated member and spaced from the inner face of said cut-out portion, whereby a securing member may be placed upon said hook when said members are unassembled, said members when assembled forming a pivotal connection for said arms, means for releasably 'securing the upper ends of said arms to gether, and means for supporting said stanchion.

2. In an animal stanchion, a pair of pivotally connected oppositely bowed arms, a lug formed on the upper end of one of said arms, a latch adapted to engage said lug when the arms are brought into engage- ;ment, said latch being carried on the upper end of the other of said arms, a second lug formed on the upper end of said first-named arm, and resilient means connected to said second-named arm cooperating with said second named lug for holding said latch in an engaged position and opemng said arms when the latch is disengaged.

3. In an animal stanchion, a pair of oppositely bowed arms pivotally connected at their lower ends, a lug formed on the upper 401 end of one of the said arms, a bifurcated member forming a housing, a pivot mounted in said housing, a lever mounted intermediate its ends on "said pivot and having a depending arm, said lever having an enlarged portion provided with an aperture adapted to receive said lug when the arms are brought into engagement, and means connected with said depending arm to hold the said lever in engagement with said lug when the arms are brought into engagement and to eject the opposite arm when the lever is disengaged.

4. In ananimal stanchion, a pair of oppoof said arms, said arms .being pivoted at their lower ends and the movement of one arm relativeto the other being restricted,

' latching means mounted at the upper end of said arms and resilient means carried by one of said arms and cooperating with the other e of said arms to operate said. latching means 'to hold the arms ina latched position and eject the unsupported arm when said latching means is disengaged.

5. In an animal stanchion, a pair of pivotally connected oppositely bowed arms, a lug formed on the upper end of one of said arms, a member secured to the upper end of the other of said arms and bifurcated to form frames for a housing, a lever pivotally mounted in said frames provided with an enlarged portion having a central aperture adapted to receive said lug, lugs formed on the enlarged portion of said lever and engaging the frames of said housing, and means for resiliently holding said lever in engagement with the lug on the upper end of the arm comprising a depending arm secured to said lever, a spring carried by said "arm and adapted to engage the upper end of into engagement. 1

6. In ananimal stanchion, a pair of oppositely bowed 5 arms pivotally connected at their lower ends, a lug formed on the'upper end of one of said arms, a member carried 'by the other of said arms and bifurcated to form side frames for housing, a pivot mounted in said frames, a lever mounted on said pivot intermediate its end and having an enlarged portion provided with an opening'adapted to receive said lug,'means for limiting the downward movement of said lever, means for resiliently holding said lever in engagement with said lug, comprising a depending arm secured centrally to the lever and carrying a spring adapted to engage the opposite arm when the arms are brought into engagement, and means for I supporting said arms,

7. In an animal stanchion, a pair of arms pivotally connected at their lower ends, a pair of lugs formed upon the upper end of one of said arms, a latch carried by the other of said arms, and resilient means carried by said latch and engaging 'one of said lugs for holding said latch in engagement with the other of said lugs, and ejecting one of said iLI'IIlS when the'latch is released from said ug. I v

"8. In ,an animal stanchion, comprising a pair of oppositely bowed arms, a pair of complementary members adapted when secured together to form a hinge for said arms, a securing member for said stanchion, means for attaching said securing member V to one of saidcomplementary members while sltely bowed arms, supportlng means for one the members are unassembled, and means carriedtby one of said complementary .members adapted to cover the plvotalconnection,

said securing means being unremovable when the complementary members are in assembled position.
